FREEI'IOLD, NEVT JERSEY PILE STRUCTURE Original application filedOctober 20, 1926, Serial No. 142,855. Divided and. this applicationfiled-August This invention relates to pile structures and particularlyto reinforcing concrete piles for use in building foundations,sea-walls, jetties, cribs and similar structures.

Various forms of reinforced interlocking piles have been designed butsuch piles are commonly constructed in such a manner that they cannot beinterchanged or reversed since the two sides of the piles difler inconstruction. For instance, one side may have a groove or socketextending longitudinally thereof and the other side may have alongitudinally extending tongue or projection adapted to fit into thesocket or groove of the adjacent pile.

This invention has for its salient object to provide areinforcedconcrete pile so constructed that it is reversible and eitherside of any pile can be interlocked with either side of any other pile.

Another object of the invention is to provide a pile structure that ischeap in construction and can be economically manufactured.

Further objects of the invention will appear from the followingspecification taken in connection with the drawings, which form a partof this application, and in which Fig. 1 is an elevational view of oneend of the pile constructed in accordance with the invention;

Fig. 2 is a transverse sectional elevation of the pile shown in Fig. 1;

Fig. 3 is an elevational view similar to Fig.

1 but showing the other end of the pile; and Fig. 4 is a sectionalelevation of a sea-wall formed from a plurality of piles constructed inaccordance with the invention.

The invention briefly described consists of a pile formed of reinforcedconcrete and having the two side edges thereof provided withlongitudinally recessed or cut away portions. Each pile has imbeddedthereon a longitudinally extending angle bar having a portion extendingbeyond the side edge of the pile and extending into the recessed or cutaway portion. The pile is so formed that the recess at one edge extendsto one face of the pile and the recess at the other end extends to theother face of the pile. The two side edges of the piles are thereforesim- Serial No. 298,142.

ilar in construction but are reversed. This provides a structure inwhich the outwardly projecting portions of the angle bars overlap whenthe pilesare positioned adjacent each other and interlocked. Cement orgrout can be poured into the interlocking joints and will fill in thespace around the interlocking ends of the angle bars.

This application is a division of application Serial No. 142,855, filedOctober 20, 1926, and in the particular form of the inventionillustrated the piles are formed of material -commonly used, such ascement, sand, broken stone or gravel, and each pile 10 has imbeddedtherein and extending longitudinally thereof reinforcing members such asrods or bars 11.

Each pile is recessed or cut away, as shown at 15 and 16, on theopposite longitudinal edges thereof, the recess 15 extending from oneface 20 and the recess 16 extending from the other face 21. Thus it willbe seen that the recesses 15 and 16 at the two edges of the pile arereversed, one extending from one face and the other from the other face.The recesses or cutaway portions provide longitudinally extendingportions 22 and 23.

An angle bar is imbedded in each side of the pile, one bar 25 extendingoutwardly into the recess 15 and having an angle or flange 26 disposedin the recess 15 and spaced from the edge of the pile. The other bar 30extends outwardly into the recess 16 and has an angularly disposedflange 31 disposed in the recess 16 and spaced from the edge of thepile.

The bars 25 and 30 are provided with openings 32 through which arepassed wires or stirrups 33.

When the piles are used for forming a wall or etty, they are interlockedas shown in Fig. 4c, the flange 26 of one of the angle bars 25overlapping the flange 31 of the angle bar 30 in the adjacent pile. Theinterlocked joints are then filled with grout or like material which ispoured into the ends 'of the joints.

Fig. 4 illustrates at 40 an interlocking joint formed between twoangularly disposed piles. This joint is similar to those alreadydescribed and differs from the structure shown in Fig. 2 only in theformation of the recess into which the outer edges of the angle barsextend. The recess 41 shown at the top of Fig. 4 is formed in one of theside faces of the pile rather than in the edge thereof.

It will be obvious from the above description that a very simple, cheapand inexpensive form of interlocking pile has been designed and thateither side of any pile can be interlocked with either side of any otherpile, the piles being reversible and interchangeable.

Although one specific embodiment of the invention has been particularlyshown and described, it will be understood that the invention is capableof modification and that changes in the construction and in thearrangement of the various cooperating parts may be made withoutdeparting from the spirit or scope of the invention, as expressed in thefollowing claims.

What I claim is:

1. A pile having oppositely extending, exactly similar, angular recessesat the two side edges thereof, and oppositely extending longitudinalangle bars embedded in the pile structure, the outer edges of the barsbeing disposed in said recesses.

2. A concrete pile having oppositely extending, exactly similar, angularrecesses at the two side edges thereof, and oppositely extendinglongitudinal angle bars formed of metal and embedded in the pilestructure, the outer edges of the bars being disposed in said recesses.

3. A pile formed of reinforced concrete and having longitudinallyextending, exactly similar, recessed portions at the sides thereof, oneportion extending to one face of the pile and the other portionextending to the other face, and longitudinally extending bars embeddedin the pile, one bar extending into each recessed portion and having anangularly disposed flange disposed in said portion.

4. A pile formed of reinforced concrete and having longitudinallyextending, exactly similar, recessed portions at the sides thereof, oneportion extending to one face of the pile and the other portionextending to the other face, and longitudinally extending bars embeddedin the pile, one bar extending into each recessed portion and having anangular ly disposed flange disposed in said portion and spaced from theside face of the recessed portion, the flanges extending in oppositedirections.

6. A pile having oppositely extending, exactly similar, longitudinallyextending recesses at its sides and an angle bar embedded in the pileand extending into each recess, each bar having a flange at its outeredge disposed in the recess.

7. A pile having oppositely extending, longitudinally extending, exactlysimilar, recesses at its sides and an angle bar embedded in the pile andextending into each recess, each bar having a flange at its outer edgedisposed in the recess, the flanges being spaced from and substantiallyparallel to the inner walls of the recesses.

In witness whereof, I have hereunto set my hand this 27th day of June,1928.
